MEAD SPIKE.

Application led September 19, 1923. Serial No. 3,373.

To all whom t mayvconcem:

Be it known that l, FREDERICK l. Harinas, a citizen of the UnitedStates, residingy at Rockville Center, Long island, in the u county ofNassau and State of New York,

have invented a new and useful Railroad Spike, of which the following isa specificatlon.

This invention relates to railway track construction, and aims toprovide novel means for locking the spikes employed for securing therails and tie plate together, the tie plate cooperating with the lockingmeans to insure against accidental displacement thereof. y

Another important object of the invention is to provide a lock of thischaracter which may he readily and easily positioned, eliminating thenecessity of making changes in the usual tie plate and tie constructionto install the same. i

i With the foregoing and other objects in y View which will appear asthe description iroceeds, the invention resides in the comination andarrangement of parts and in the, details of construction hereinafter delscribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may he made within thescope of what is claimed, without departing from the spirit di theinvena tion.

Referring to the drawing:

Figure 1 is a sectional view through a :n.3 rail and fastening spikeconstructed in accordance with the invention.

Figure 2 is a perspective view of the spike.

Figure 3 is a perspective view of the lockingkl pin employed isconnection with the sp1 e.

IReferring to the drawing inl detail, the reference character 5designates a railway tie which is of the usual and well knownconstruction, and on which the tie plate is positioned.

IThe tie plate is formed of metal, and provides a rest for the rail 7,to protect the tie 5 and eliminate any possibility of the rail digginginto the tie to weaken the same.,

ormed in the tie plate d are the usual spike openings, through which thespikes pass, when positioned on a tie, the spike in the present showingbeing indicated at 8.'

As shown, the spike, which forms an important feature of the inventionis formed with the usual head 9 that contacts with the hase of the railassociated therewith to secure the rail in position.

Formed in one of the surfaces of the spike is a longitudinal Vgroove 10that extends from the head 9, to a point an appreciable distance fromthe head as clearly shown by Figure 1 of the drawing. lThe rear wall ofthe groove 10 is disposed at an oblique angle, at the lower end thereof,providing an inclined wall 11 presenting a cam surface to bend the pin12 positioned in the groove. lt will he noted that the inclined wall 11of the groove lies in such relation with the edge 13 of the spikeopening in the tie plate that the pin 12 which is driven into the groovebends at an oblique angle adjacent to the edge 13 to lock the spikeagainst accidental displacement. Y l

lt might be further stated that the pin 12 is formed of suitable metal,so that the spike will bend readily when the beveled end thereofcontacts with the inclined wall of the spike. To insure the hendingaction of the pin 12, one end thereof is heveled at 11iwhereby thebeveled end will he deflected' laterally when driven into the spike.

1. A rail fastening device including a tie plate having a spike opening,a spike positioned in the xopening, said spike having a Groove formed inone edge thereof, an 1nclined wall formed at the lower end of thegroove, a locking pin adapted to he -ositioned in the groove', saidlocking pin. a apted to extend laterally when driven into the and saidlocking pin being of a groove, thickness equal to the space between theinclined wall and adjacent edge of the spike opening of the tie plate.

2. ln a rail fastening device, a tie plate having a spike opening, aspike adapted to extend into the spike opening, said spike having avgroove formed along one edge thereof, said groove having an end' wallextending at an oblique angle with respect to the side walls thereof,and a locking pin adapted to he driven into the groove and extendedlaterally by its contact ywith the angular wall of the groove.

3. 1n a rail fastening device, the comhi nation of a tie plate having aspike opening,
